I am trying to blink a character, which indicates which parameter you are changing with your potentiometer. Is this possible? I know I can blink a cursor, but I need to blink a single digit of a 4 digit number. Any ideas?
Write the character, reposition the cursor, write a space, reposition the cursor...repeat ad infinitum.
I got it working doing almost the same thing. I printed the number, repositioned the cursor to the same spot, then did lcd.blink, then repeated....Thanks!
